DID YOU KNOW
Ascon monitors air quality 24/7 onsite and offsite in nearby neighborhoods.
Onsite monitoring has been conducted since active work initiated for the final cleanup January 2019 and there has been air monitoring during all prior field work. Neighborhood monitoring stations have been in place for over two years, providing a baseline of data which confirms that there is no offsite public health risk from the Ascon project, during both active field work and inactive times. DTSC has stated “air quality monitoring results do not indicate a threat to public health”. You can view recent and historical air quality monitoring data at Actively Monitoring Air Quality on asconhb.com.
MAINTENANCE: Regular maintenance will be conducted within the Site and around the perimeter fence areas, including gate areas.
SECURITY: 24-hour onsite security continues. Security is not always visible at the entrance gates. In addition to 24/7 onsite security, there are regular visits by air quality technicians, Site inspectors, and Site maintenance personnel. Unannounced visitors without official business or agency oversight of Ascon are not permitted to enter the Site. Trespassers will be reported to the Huntington Beach Police Department and DTSC.

DRONES: The community is asked to not fly drones over the Ascon when there is active work. This could create worker and Site safety issues. We appreciate the community’s assistance by preventing drone flights over sensitive onsite equipment and the power lines along the perimeter of Ascon.
ENTRANCE AND EXIT GATES: Entering the Ascon site is prohibited to those who are not authorized. The community is asked to keep a safe distance from both entrance and exit gates at Ascon, and refrain from parking, walking, or standing in these areas. The gates on Magnolia Street and Hamilton Avenue may open unexpectedly for workers conducting air monitoring and site inspections, as well as supply delivery and removal.
PEDESTRIANS: Pedestrians have been observed walking next to Ascon along Magnolia and Hamilton streets next to the concrete fence base where there currently is no sidewalk. We encourage pedestrians to use the sidewalks on the east side of Magnolia and the north side of Hamilton.
BICYCLISTS: Please “Share the Road” and be aware of bicyclists using Hamilton Avenue and Magnolia Street. The Ascon project has installed additional signage to guide those using the bike lane.
PHYSICAL DISTANCING: Work at Ascon is being conducted under Site safety protocols regarding COVID-19 and ongoing protocols and procedures to maintain job safety. These practices apply to air quality professionals and other team members who may be outside the fence conducting work. We ask for the community’s support of these safety practices by maintaining physical distancing to allow these professionals to focus on their work and stay safe.
